<h2><a name="About"></a>About Ghostscript fonts</h2>

<p>
Ghostscript is distributed with two kinds of files related to fonts:

<ul>
<li>the fonts themselves in individual files, and
<li>a file &quot;<code>Fontmap</code>&quot; that defines for
Ghostscript which file represents which font.
</ul>

<p>
Additionally, the file <code>cidfmap</code> can be used
to create substitutes for CIDFonts referenced by name in Postscript and PDF jobs.
See the section on <a href="Use.htm#CIDFontSubstitution">CID Font Substitution</a>
for details. NOTE: care must be exercised since poor or incorrect output may result
from inappropriate CIDFont substitution. We therefore <strong>strongly</strong> recommend
embedding CIDFonts in your Postscript and PDF files if at all possible.

<p>
The &quot;base 35&quot; fonts required for Postscript (and "base 14" required for PDF)
are Postscript Type 1 font files.
<p><a name="Fontmap"></a>
When Ghostscript needs a font, it must have some way to know where to look
for it: that's the purpose of the <code>Fontmap</code> file, which
associates the names of <em>fonts</em> such as <code>/Times-Roman</code>
with the names of font <em>files</em>, such as
<code>n021003l.pfb</code>.  <code>Fontmap</code> can also create
aliases for font names, so that for instance,
<code>/NimbusNo9L-Regu</code> means the same font as
<code>/Times-Roman</code>.

<hr>

<h2><a name="Free_fonts"></a>Ghostscript's free fonts</h2>
<ul>
<li>35 commercial-quality Type 1 basic PostScript fonts -- Times,
Helvetica, Courier, Symbol, etc. -- contributed by URW++ Design and
Development Incorporated, of Hamburg, Germany
(<a href="http://www.urwpp.de/">http://www.urwpp.de/</a>).  Fontmap names
them all.
</ul>

<h2><a name="Get_fonts"></a>How Ghostscript gets fonts when it runs</h2>

<p>
Fonts occupy about 50KB each, so Ghostscript doesn't load them all
automatically when it runs.  Instead, as part of normal initialization
Ghostscript runs a file <code>gs_fonts.ps</code>, which arranges to load
fonts on demand using information from the font map.  To preload all of the
known fonts, invoke the procedure

<blockquote><code>
loadallfonts
</code></blockquote>

<p>
The file <code>lib/prfont.ps</code> contains code to print a sample page of
a font.  Load this program by including it in the <code>gs</code>
command line or by invoking

<blockquote><code>
(prfont.ps) run
</code></blockquote>

<p>
Then to produce a sampler of a particular font XYZ, invoke

<blockquote><code>
/XYZ DoFont
</code></blockquote>

<p>For example,

<blockquote><code>
/Times-Roman DoFont
</code></blockquote>

<p>
For more information about how Ghostscript loads fonts during execution,
see <a href="Use.htm#Font_lookup">here</a>.

<hr>

<h2><a name="Add_fonts"></a>Adding your own fonts</h2>

<p>
Ghostscript can use any Type 0, 1, 3, 4, or 42 font acceptable to
other PostScript language interpreters or to ATM, including MultiMaster
fonts. Ghostscript can also use TrueType font files.

<p>
To add fonts of your own, you must edit Fontmap to include at the end an
entry for your new font; the format for entries is documented
in Fontmap itself.  Since later entries in Fontmap override earlier
entries, a font you add at the end supersedes any corresponding fonts supplied
with Ghostscript and defined earlier in the file. To ensure correct output,
it is vital that entries for the &quot;base 35&quot; fonts remain intact
in the Fontmap file.

<p>
In the PC world, Type 1 fonts are customarily given names ending in
<code>.PFA</code> or <code>.PFB</code>.  Ghostscript can use these
directly: you just need to make the entry in Fontmap.  If you want to use
with Ghostscript a commercial Type 1 font (such as fonts obtained in
conjunction with Adobe Type Manager), please read carefully the license that
accompanies the font to satisfy yourself that you may do so legally; we take
no responsibility for any possible violations of such licenses.  The same
applies to TrueType fonts.

<h3><a name="Convert_BDF"></a>Converting BDF fonts (- deprecated!)</h3>

<p>
Ghostscript provides a way to construct a (low-quality) Type 1 font from a
bitmap font in the BDF format popular in the Unix world.  The shell script
<code>bdftops</code> (Unix) or the command file
<code>bdftops.bat</code> (DOS) converts a BDF file to a
scalable outline using <code>bdftops.ps</code> .  Run the
shell command

<blockquote><code>
bdftops&nbsp;BDF_filename&nbsp;[AFM_file1_name&nbsp;...]&nbsp;gsf_filename&nbsp;fontname<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;UniqueID&nbsp;[XUID]&nbsp;[encodingname]
</code></blockquote>

<p>
The arguments have these meanings:
<blockquote><table cellpadding=0 cellspacing=0>
<tr valign=top>	<td><code>BDF_filename</code>
	<td>&nbsp;&nbsp;
	<td>Input bitmap file in BDF format
	<td>&nbsp;&nbsp;
	<td>&nbsp;
<tr valign=top>	<td><code>AFM_file1_name</code>
	<td>&nbsp;
	<td>AFM files giving metrics
	<td>&nbsp;
	<td>(Optional)
<tr valign=top>	<td><code>gsf_filename</code>
	<td>&nbsp;
	<td>Output file
	<td>&nbsp;
	<td>&nbsp;
<tr valign=top>	<td><code>fontname</code>
	<td>&nbsp;
	<td>Name of the font
	<td>&nbsp;
	<td>&nbsp;
<tr valign=top>	<td><code>UniqueID</code>
	<td>&nbsp;
	<td>UniqueID (<a href="#Unique_IDs">as described below</a>)
	<td>&nbsp;
	<td>&nbsp;
<tr valign=top>	<td><code>XUID</code>
	<td>&nbsp;
	<td>XUID, in the form <code>n1.n2.n3...</code> (<a href="#Unique_IDs">as described below</a>)
	<td>&nbsp;
	<td>(Optional)
<tr valign=top>	<td><code>encodingname</code>
	<td>&nbsp;
	<td>"StandardEncoding" (the default), "ISOLatin1Encoding",<br>"SymbolEncoding", "DingbatsEncoding"
	<td>&nbsp;
	<td>(Optional)
</table></blockquote>

<p>
For instance

<blockquote><code>
bdftops&nbsp;pzdr.bdf&nbsp;ZapfDingbats.afm&nbsp;pzdr.gsf&nbsp;ZapfDingbats&nbsp;4100000&nbsp;1000000.1.41
</code></blockquote>

<p>
Then make an entry in Fontmap for the <code>.gsf</code>
file (<code>pzdr.gsf</code> in the example) as
<a href="#Add_fonts">described above</a>.

<h2><a name="For_developers"></a>For developers only</h2>

<p>
The rest of this document is very unlikely to be of value to ordinary
users.

<h3><a name="Font_contents"></a>Contents of fonts</h3>

<p>
As noted above, Ghostscript accepts fonts in the same formats as PostScript
interpreters.  Type 0, 1, and 3 fonts are documented in the PostScript
Language Reference Manual (Second Edition); detailed documentation for Type
1 fonts appears in a separate Adobe book.  Type 2 (compressed format) fonts
are documented in separate Adobe publications.  Type 4 fonts are not
documented anywhere; they are essentially Type 1 fonts with a BuildChar or
BuildGlyph procedure.  Types 9, 10, and 11 (CIDFontType 0, 1, and 2) and
Type 32 (downloaded bitmap) fonts are documented in Adobe supplements.
Type 42 (encapsulated TrueType) fonts are documented in an Adobe
supplement; the TrueType format is documented in publications available
from Apple and Microsoft.  Ghostscript does not support Type 14 (Chameleon)
fonts, which use a proprietary Adobe format.

<h3><a name="Unique_IDs"></a>Font names and unique IDs</h3>

<p>
If you create your own fonts and will use them only within your own
organization, you should use <code>UniqueID</code> values between
4000000 and 4999999.

<p>
If you plan to distribute fonts, ask Adobe to assign you some UniqueIDs and
also an <code>XUID</code> for your organization. Contact

<blockquote><address>
Unique ID Coordinator<br>
Adobe Developers Association<br>
Adobe Systems, Inc.<br>
345 Park Avenue<br>
San Jose, CA  95110-2704<br>

<a href="mailto:fontdev-person@adobe.com">fontdev-person@adobe.com</a><br>
</address></blockquote>

<p>
The XUID is a Level 2 PostScript feature that serves the same function as
the UniqueID, but is not limited to a single 24-bit integer.  The
<code>bdftops</code> program creates XUIDs of the form
"<code>[-X-&nbsp;0&nbsp;-U-]</code>" where "<code>-X-</code>" is the
organization XUID and "<code>-U-</code>" is the UniqueID.  (Aladdin
Enterprises' organization XUID, which appears in a few places in various
font-related files distributed with Ghostscript, is 107; do not use this for
your own fonts that you distribute.)
